Grade A Sodium Ion Battery 3.0V 200AH Na-ion Prismatic Cell for EV Golf Cart Marine Energy Storage
About Sodium Ion Battery
Sodium ion battery is a kind of rechargeable battery which is very good alternative to lead acid battery and has great potential to replace lithium ion battery in certain applications. Its working principle is similar to lithium ion battery, with Na+ moving back and forth between the positive pole and negative pole. Sodium ion battery have apparent advantages in low and high temperature performance, safety and cost. Research on sodium ion battery can date back to 1970s. Based on the development of technology and superior features of sodium ion battery itself, it has attracted widespread attention in recent years. Sodium ion battery has been put into mass production and adopted in energy storage system and electric vehicles in China.

Advantages
1. Cost advantage
On the one hand, sodium resources are much more abundant than lithium resources in the earth crust, so sodium ion battery has advantages on its raw material cost. On the other hand, the production process of sodium ion battery is very similar to lithium ion battery, and the manufacturing equipments for lithium ion battery are partially compatible to sodium ion battery. It also helps to reduce the production cost.
2. Wide temperature range
Sodium ion batteries can work in a wide temperature range, which can be charged under temperature of -10°C ~ 60°C and discharge under temperature of -30°C ~ 60°C. Excellent performance under low temperature is a highlight of sodium ion battery, and it is especially suitable for the cold regions and outdoor applications. As test result shows, when sodium ion batteries discharge at 0.5C at the temperature of -20°C, the discharge capacity is more than 80%.
3. Better safety and environmental protection
Sodium ion batteries are more stable than lithium ion batteries. Sodium ion batteries generate less heat when in short circuit, and aluminum negative electrode is less likely to overdischarge. They can even discharge to 0V without damaging the battery. Therefore, sodium ion batteries have better stability and safety than lithium ion batteries, even in extreme conditions such as high temperature, overcharge and overdischarge etc. In addition, the positive and negative electrode materials of sodium ion batteries usually use non-toxic metals and inorganic substances, and the electrolyte is also relatively stable. Sodium ion batteries are environmentally friendlier to some extent.
4. Long cycle life
Lead acid batteries only have cycle life of 300~600 times, and they need to be replaced after being used for 1 or 2 years. While cycle life for sodium ion batteries can be up to 4000 times, which is comparable to lithium ion batteries. With long cycle life and higher cost effectiveness, sodium ion battery is a perfect alternative to lead acid battery and even lithium ion battery.
